| Abstract: | Based on self-recurrence method and Fresnel-Kirchhoff diffraction formula,we have studied eigen modes and their beam quality factor M2 in the large-aperture high-power thin disk laser with gain distribution,aperture stop and tilt mirror,etc.By using eigenvector method.The large-aperture thin disk kilowatt laser system and fiber-scan measurement device is developed.The output characteristics of large-aperture thin disk laser have been studied both experimentally and theoretically.The results show that large-... |
